Hot-dipped galvanized (GI) H beams are structural steel beams that have been coated with a layer of zinc through the process of hot-dip galvanization. This coating provides enhanced corrosion resistance and extends the lifespan of the beams, making them suitable for outdoor and high-moisture environments. Here's some information about the quality, technique, and dimensions of hot-dipped GI H beams:

Quality: Hot-dipped GI H beams are manufactured from high-quality structural steel, ensuring strength, durability, and structural integrity. The galvanization process adds an additional layer of protection, making them resistant to rust and corrosion. The quality of hot-dipped GI H beams is further assured through adherence to relevant industry standards and quality control measures.

Technique: The hot-dip galvanization technique involves immersing the H beams in a bath of molten zinc, allowing the zinc to bond with the steel surface. This forms a protective layer that acts as a barrier against corrosive elements. The technique ensures a uniform and consistent coating, providing long-lasting protection to the H beams.

Dimensions: Hot-dipped GI H beams are available in various dimensions to suit different structural requirements. The specific dimensions may vary based on the manufacturer or supplier. However, the dimensions typically include the height (H), width (B), and flange thickness (t). For example:

• H150 x B75 x t6: Height - 150mm, Width - 75mm, Flange Thickness - 6mm
• H200 x B100 x t8: Height - 200mm, Width - 100mm, Flange Thickness - 8mm
• H300 x B150 x t10: Height - 300mm, Width - 150mm, Flange Thickness - 10mm

It's important to consult with the manufacturer or supplier for precise dimensions and available sizes of hot-dipped GI H beams, as they may have variations in their product offerings.

Hot-dipped GI H beams are commonly used in various construction and structural applications, including building frames, bridges, warehouses, and industrial structures. They provide reliable support, load-bearing capacity, and resistance to corrosion, making them a popular choice for outdoor and exposed environments.
